Achillion Reiterates HCV Pipeline Priorities and Reports Third Quarter and Nine Month 2013 Financial Results

NEW HAVEN, Conn., Nov. 12, 2013 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq:ACHN) today reported financial results for the three and nine months ended September 30, 2013 and provided an update on the Company's portfolio of direct-acting antiviral compounds being developed for the treatment of chronic hepatitis C virus (HCV).

For the third quarter of 2013, Achillion reported a net loss of $13.9 million or $0.14 per share, compared with a net loss of $15.3 million or $0.20 per share for the third quarter of 2012. Cash, cash equivalents, marketable securities, and interest receivable as of September 30, 2013 were $173.1 million.

"Over the next few months our priority is to advance our proprietary assets through critical milestones, including the completion of the preclinical work necessary to initiate first-in-human trials with ACH-3422, our uridine-analog nucleotide prodrug, for the potential treatment of chronic HCV," commented Milind S. Deshpande, Ph.D., President and Chief Executive Officer of Achillion. "Furthermore, we intend to engage in regulatory discussions regarding the path forward for sovaprevir, which remains on clinical hold, and in parallel, we plan to initiate early next year a drug-drug interaction study followed by a therapeutic trial to evaluate our differentiated NS5A inhibitor, ACH-3102, in combination with our macrocyclic protease inhibitor, ACH-2684."

Dr. Deshpande further commented, "We believe that our current cash balance of approximately $173 million will be more than sufficient to reach several value creating milestones and fund our operations for at least two years."

Third Quarter Results

For the three months ended September 30, 2013, Achillion reported a net loss of $13.9 million compared with a net loss of $15.3 million during the same period of 2012. The Company recognized no revenues for the three months ended September 30, 2013 nor any during the same period in 2012.

Research and development expenses were $11.3 million for the three months ended September 30, 2013, compared with $12.6 million for the same period of 2012. The decrease for the three months ended September 30, 2013 was primarily due to decreased manufacturing costs associated with sovaprevir and decreased clinical costs associated with ACH-2684, offset by increased clinical trial costs related to ACH-3102 and the combination trial evaluating sovaprevir and ACH-3102. For the three months ended September 30, 2013, general and administrative expenses were $2.7 million, compared with $2.6 million incurred during the same period in 2012. The increase in general and administrative expenses was primarily due to an increase in non-cash charges related to stock based compensation and increased business development consulting fees.

Non-cash stock compensation expense totaled $1.2 million for the third quarter of 2013 as compared with $934,000 for the third quarter of 2012 and is included in research and development and general and administrative expenses.

Nine Month Results

For the nine months ended September 30, 2013, Achillion reported a net loss of $45.6 million, an increase from a net loss of $35.9 million in the same period in 2012. There were no revenues during the first nine months of 2013, compared with $2.5 million in the prior year period. Revenue during the first nine months of 2012 was related to recognition of deferred revenue under the Company's former collaboration with Gilead Sciences, Inc.

For the nine months ended September 30, 2013, research and development expenses totaled $36.6 million, compared with $30.6 million during the same period in 2012. Research and development expenses increased primarily due to increased costs related to combination clinical trials and drug interaction studies of sovaprevir and ACH-3102, increased costs related to the ACH-3422 preclinical studies as well as increased scientific consulting fees. Personnel costs and non-cash charges related to stock based compensation also increased primarily due to the addition of personnel in our development group. General and administrative expenses were $9.4 million for the nine months ended September 30, 2013, increased from $8.0 million in the same period in 2012. The increase in general and administrative expenses was primarily due to an increase in non-cash charges related to stock based compensation combined with increased business development consulting fees.

Non-cash stock compensation expense totaled $4.3 million for the nine months ended September 30, 2013 as compared with $2.7 million for the same period in 2012, and is included in research and development and general and administrative expenses.

About HCV

The hepatitis C virus is the most common cause of viral hepatitis, which is an inflammation of the liver. It is currently estimated that more than 170 million people are infected with HCV worldwide including more than 5 million people in the United States, making HCV more than twice as widespread as HIV. Three-fourths of the global HCV patient population is undiagnosed; it is a silent epidemic and a major global health threat. Chronic hepatitis, if left untreated, can lead to permanent liver damage that can result in the development of liver cancer, liver failure or death. Few therapeutic options currently exist for the treatment of HCV infection. The current standard of care is limited by its specificity for certain types of HCV, significant side-effect profile, and injectable route of administration.
